Title: Sinusoidal wave generating circuit
Inventor: SHIMADA MASUMITSU
IPC: H03B28/00
Filed: 1989-03-13
Abstract: PURPOSE:To obtain a stable sinusoidal wave even to a temperature change with simple constitution by providing a square wave oscillator outputting a square wave at a nearly power voltage, an integration device integrating the square wave and outputting a triangle wave, a waveform shaping device and a low pass filter correcting the waveform distortion of the sinusoidal wave. CONSTITUTION:An oscillator 34 is oscillated in self-running and generates a square wave at a nearly power voltage and the square wave is inverted by an inverter gate 41 of an integration device 40. Since the oscillator 34 is so- called in the oscillating state of the power voltage, and when a stabilized voltage supply is used for the power supply, the square wave is not almost fluctuated against temperature. Then charge/discharge is repeated for a capacitor 43 with an output of the inverter gate 41. The square wave is converted into a nearly symmetrical triangle wave through the repetition and inputted to an inverter gate 45 of a waveform shaping device 44. Moreover, the sinusoidal wave outputted from the inverter gate 45 is inputted to the low pass filter 46., the waveform distortion at the apex of the wave is corrected and the stable sinusoidal wave with less harmonics is outputted.

Abstract: PURPOSE:To simplify the configuration by reading a color signal of a picture signal in the unit of blocks to generate a luminance signal and color difference signals in the unit of blocks and applying DCT arithmetic operation to them thereby eliminating the need for a block processing memory and a multiplexer circuit. CONSTITUTION:A read circuit 35 reads 8 line horizontal picture element signals, that is, a color signal G (luminance signal Y) for one block from a solid-state image pickup element 25 and a DCT arithmetic operation circuit 33 applies DCT arithmetic operation to the signal. Then changeover switches 26, 31 are switched to read a color signal R by one block and given to a subtractor circuit 27, in which the signal resulting from the color signal G read before delayed at a 1 block delay circuit 28 is subtracted from the signal R to generate a color difference signal R-Y, and it is subject to DCT arithmetic operation in the circuit 33. Similarly, switches 26, 31 are selected to generate a color difference signal B-Y. Thus, each color signal is read in the unit of blocks to generate the luminance signal and the color difference signal in the unit of blocks and they are subject to DCT arithmetic operation and then a block processing memory and a multiplexer circuit are not required to simplify the configuration.

Title: Facsimile unit
Inventor: WATANABE ASAO
IPC: H04N1/00
Filed: 1979-05-18
Abstract: PURPOSE:To make small the size of unit and to decrease the cost, by using the modulator and VSB filter used at transmission, for the demodulation and the rejection of harmonics at reception respectively. CONSTITUTION:At transmission, the video signal obtained through the scanning of original 25a with the image sensor 25 is the modulation signal rejected for high frequency componets by means of the MODEM34, VSB filter 35 through the switch 30a and via the binary-ternary value conversion circuit 26, amplitude control circuit 28 and LPF29, and is transmitted to the line 39 via the switch 32a and NCU38. At reception, the switches 30-32 are respectively selected to the positions 30b- 32b. The input signal from NCU38 passes through the AGC circuit 42, is demodulated at the MODEM34 with the carrier signal extracted at the carrier extracting circuit 43, is rejected for the high frequency components at the VSB filter 35, and is input to the ternary-binary value conversion circuit 44.

Title: Paper feeding device
Inventor: FUKUI KAZUYUKI
IPC: B65H3/54
Filed: 1980-05-09
Abstract: PURPOSE: To make it possible to positively feed sheets of different spring characteristics piece by piece, in a device in which sheets piled up in a paper feeding cassette are sent out one by one, by pressing the topmost sheet downwardly by a pressure-applying member to control bending shape of the sheet.  
     CONSTITUTION: When a paper-feeding roller 9 rotates, the topmost sheet P 1  contacting this roller is sent out in the direction of the arrow. At this time, since both corner sections on the tip of this sheet P 1  are prevented from forwarding by a separating fork 6, the sheet is bent causing a bend L to the rear of the separating fork 6 toward the paper feeding direction. On the other hand, as a side roller 8 (pressure-applying member) provided on a free-to-rotate arm 7 is pressing both end sections of the sheet downwardly by the gravity, the bent L to be formed in the rear of the separating fork 6 is controlled to a certain extent. Now, when the paper- feeding roller 9 keeps on rotating, the both corner sections on the tip of the sheet P 1  go over the separating fork 6, and only the topmost sheet P 1  is separated and sent out.

Abstract: PURPOSE:To make it possible to implement high integration of elements, by providing transfer gate transistors on driver transistors so that they are over lapped. CONSTITUTION:The voltages of a pair of bit line BL and the inverse of BL are made to be a power source voltage or a high voltage similar to the power source voltage. Data are kept by transistors T1-T4 by this method. In the writing operation, at first, a word line WL is made to become a high potential and the transistors T3 and T4 are conducted. The bit lines BL and the inverse of BL are made to be H/L or L/H in correspondence with the data. Thus, the state of the flip-flop of the transistors T1-T4 is determined. Then, the potential of the word line is lowered, and the transistors T3 and T4 are made nonconducting and are returned to a high potential together with the bit line. In the reading operation, at first, the word line is made to be the high potential, and the transistors T3 and T4 are made to be a conducting state. The decrease of either potential of the bit line BL or the inverse of BL is detected in corre spondence with the state in a memory cell, and the data is read out. Thereafter, the word line is returned to the low potential, and both bit lines BL and the inverse of BL are returned to the high potential.

IPC: B21J9/06
Filed: 1982-04-13
Abstract: PURPOSE:To prevent frequent occurrences of defective products, by detecting the change of pressing force applied to a piercing pin by a strain gauge and thereby recognizing the degree of wear of the pin. CONSTITUTION:With the progress of wear of the head 11 of a piercing pin, the hole diameter of a pierced blank 13 becomes gradually smaller, and at last, simultaneously with the completion of piercing, the pierced blank bites the shoulder 14 of the peripheral body with high pressure, and more pressing force acts on the shoulder 14 from the whole periphery. Accordingly, at upper limit position of advance of a punch 18, once lowered pressing force is raised again. An upward change of pressing force is directly reflected by a strain gauge 20. When wear reaches the limit, the machine is stopped at once, and the piercing pin 10 is replaced with new one.

IPC: G11B7/26
Filed: 1995-03-22
Abstract: PURPOSE: To produce a stamper of excellent quality for an optical disk with a simple equipment without corroding a machine in the processes of forming a recessed and projected pattern by using a photoresist and forming a metal film on the pattern by electroless plating method, by preliminarily adding a palladium compd. to the photoresist. CONSTITUTION: Before a metal film is formed by electroless plating method on a photoresist with addition of palladium, the photoresist is treated with a reducing agent soln. to reduce the palladium ion near the surface into metal palladium. The photoresist is cleaned with water and then dipped in an electroless plating soln. The metal ion in the plating liquid is precipitated as the metal and spread over the photoresist surface having the recessed and projected pattern to form a metal film. The formed metal film has a function as an electrode for electric plating in the succeeding process. Since the reducing agent soln. is not corrosive, the machine is not corroded and no ventilation equipment is necessary, which means the cost for maintenance and equipments is low.
